EXPERIMENTAL INVESTIGATION OF THE EFFECT OF PRODUCT TEMPERATURE CLASSES ON ENERGY CONSUMPTION IN A CLOSED DISPLAY REFRIGERATOR
Abstract
In this study, the energy consumption of a vertical closed display refrigerator (680 Liters) in day-night modes and in different product temperature classes was experimentally investigated. Closed display refrigerator works with R290 (propane) refrigerant. Moreover, non-adiabatic capillary tube (suction line heat exchanger) system is used in the vapor compression refrigeration cycle. The experimental setup was carried out and calibrated in accordance with the TS EN ISO 22044:2022 standard. Experiments were carried out for 24 hours in a test room providing a temperature of 25°C ± 0.8°C and a relative humidity of 60% ± 2%. The commercial refrigerator has been tested under full load (700 pcs. 330 ml cans), in day and night modes, and in two different temperature classes (K1 and K4). Can temperatures which tested in the K1 temperature class were kept between 0°C-7°C. These temperature values for the K4 temperature is between 1°C-9°C. In the experiments of the K1 temperature class, 3.255 kWh/24h and 1.379 kWh/24h energy were consumed during the day and night, respectively. In the experiments of K4 temperature class, these values were measured as 3.089 kWh/24h in day mode and 1.341 kWh/24h in night mode. As a result, the energy consumption in the K1 temperature class was 5.37% and 2.83% higher in day and night modes, respectively, compared to the K4 temperature class.

TİCARİ BİR SOĞUTUCUDA ÜRÜN SICAKLIK SINIFLARININ ENERJİ TÜKETİMİNE ETKİSİNİN DENEYSEL OLARAK İNCELENMESİ
Abstract
Bu çalışmada, 680 litre hacim kapasiteli dikey, kapalı ve ısı cam kapılı bir ticari kutu soğutucusunun gece-gündüz modlarında ve farklı ürün sıcaklık sınıflarındaki enerji tüketimi deneysel olarak incelenmiştir. Ticari kutu soğutucusu R290 (propan) soğutma akışkanı ile çalışmakta ve buhar sıkıştırmalı soğutma çevrimi içerisinde adyabatik olmayan kılcal boru (emiş hattı ısı değiştiricisi) sistemi kullanılmaktadır. Deneysel düzenek, TS EN ISO 22044:2022 standartına uygun olarak kalibre edilmiş ve kurulmuştur. Deneyler, 25°C ± 0.8°C sıcaklık ve %60 ± %2 bağıl nem sağlayan bir iklimlendirme odasında 24 saat boyunca gerçekleştirilmiştir. Ticari soğutucu tam yük altında (700 adet 330 ml kutu), gece - gündüz modlarında ve iki farklı sıcaklık sınıfında (K1 ve K4) test edilmiştir. K1 ve K4 sıcaklık sınıfları, alüminyum içecek kutularının test sürecindeki sıcaklıklarını ifade eden bir test standartıdır. K1 sıcaklık sınıfında test edilen kutu sıcaklıkları; 0°C-7°C ve K4 sıcaklık sınıfında test edilen kutular ise; 1°C-9°C sıcaklıkları arasında kalması sağlanmıştır. K1 sıcaklık sınıfına ait deneylerde gündüz ve gece sırasıyla, 24 saatte 3.255 kWh ve 1.379 kWh enerji harcanmıştır. K4 sıcaklık sınıfına ait deneylerde ise bu değerler gündüz modunda 3.089 kWh ve gece gece modunda 1.341 kWh olarak ölçülmüştür. Sonuç olarak, K1 sıcaklık sınıfındaki enerji tüketimi K4 sıcaklık sınıfına göre gündüz ve gece modlarında sırasıyla %5.37 ve %2.83 daha yüksek ölçülmüştür.
